A test tube becomes cool to the touch.

Explanation:

The signs for an endothermic reaction would most likely be that a test tube becomes cool to touch. An endothermic reaction is a reaction in which heat is absorbed from the environment.

  • At the end of this heat change, the surrounding becomes colder.
  • Most endothermic reactions are always shown by the test tube becoming colder.
  • For exothermic reaction in which heat is given off to the surroundings, the tube should be hotter.
